Material properties

ASTM A128 Grade D manganese steel, designated UNS J91459, is known for its high toughness, ductility, and excellent wear resistance. It is a high manganese austenitic steel that is often used in high-wear applications where durability and longevity are crucial. The steel's unique properties arise from its high manganese content, which significantly improves its hardness and wear resistance under high impact conditions

Advantage

1. Excellent wear resistance.
2. High toughness.
3. Good ductility.
4. Resistant to deformation.
5. High impact strength.

ASTM A128 Grade D/ UNS J91459  application

ASTM A128 Grade D manganese steel is extensively used in industries where high durability and wear resistance are essential. Common applications include mining machinery, where components are exposed to harsh environments and frequent impacts. It is also used in the manufacture of crusher parts, railroad components, and heavy-duty automotive parts. Its ability to withstand high impact and abrasive wear makes it suitable for heavy-duty engineering applications.
